Classe Mods

I have a CA-200 (late model with the 201 guts) that is beginning to cry for an upgrade. Does anyone know of some shops with good mods for the Classe amps.
Rather than modding your amp and destroying its' resale value, why not just sell in here and use the funds towards a new amp? Just my 2 cents, whichever route you go good luck.
Someone on Audiogon is selling a Classe Amp, that had alot of mods to it.
